Wind energy requires a certain amount of sustainedwind speeds to be effective.
风能需要一定量的持续风速才能起作用。

A natural way to think of it would be analogous to the saffir-simpson hurricane scale that is based on maximum sustainedwind speed.
一种自然的思考方式是比照基于最高持续风力的萨菲尔—辛曾森飓风等级。

Since it is sustained by the wind and tide energy input to the oceans, diapycnal mixing coefficient (DMC) will vary along with the change of external energy input.
